was in charge of the prison where he died

Technically the president delegates that to his Attorney General, who in this case was the son of the guy who first hired a totally unqualified Epstein (21 years old, no college degree) to be around high school age kids, where he was known for ogling girls and somehow showing up to student parties where there was underage drinking.

And some blame lays with the prosecutor back in 2008 when Epstein was first charged for sex trafficking and sexual assault, who decided to let Epstein agree to a secret plea deal for only 13 months in county jail (which is really weird for a federal prosecutor to let happen), who, oh wait, was then rewarded by becoming a cabinet official for Trump.

High voltage DC lines lose about 3% per 1000km, so this project with 4300km of lines could theoretically be set up to lose 12% in losses. There's also some experimentation with ultra high voltages that would be more efficient, but probably more complex to engineer.

The "Stan Kelly" persona itself is a fictional satire. The work is actually done by cartoonist Ward Sutton, whose standard political cartoons under his own name criticize the right wing directly.

Yeah, evolving lungs ended up clearing the way to make use of the much more plentiful oxygen in the air compared to what is dissolved in water. Amphibians and reptiles have pretty low metabolisms, but birds and mammals basically evolved endothermy (aka warm bloodedness), probably in support of much higher muscular power output. Ectotherms (aka cold blooded animals) have metabolisms that are correlated to temperature, which means they can't exert themselves as well when it's cold. Endothermy allowed animals to be warm all the time, and therefore use higher muscular power output in any environment, especially sustained.

That means mammals and birds were able to cover more distance, and survive in places where reptiles and amphibians can't, and all the advantages that carries.

This article estimates at a 40kg sailfish uses about 2.7 megajoules per day of energy when hunting. That's about 650 kcal.

An 80kg human weighs about twice as much and needs about 3 times the energy, without even exertion.

Warm blooded animals spend a lot of energy just maintaining body temperature. Plus water doesn't have very much oxygen in it, compared to the atmosphere.

There's not enough oxygen in water to support our metabolisms, even if we had gills.

Fish are adapted to conserve and use less oxygen, from slower metabolic rates to more options for anaerobic respiration that doesn't poison oneself from within.

One is something you choose to pay, the other you get shot if you don't pay.

Contract claims and property claims are ultimately enforceable by government force, as well. A "no trespassing" or "no loitering" sign, or a "Copyrighted work, all rights reserved" notice is enforceable by men with guns, too.

If taxation is theft, the same reasoning would extend to property being theft, too.

40x the kinetic energy. Now consider the chemical energy stored in sufficient fuel for a coast to coast flight of that weight and speed.

Same vibes as Kim Jong Un touring a factory.

So even with those ultra unrealistic assumptions (100kg people, 1 step per second, 100% efficient energy capture), 9.8 watts just isn't enough.

Lighting needs about 0.6 watts per square foot (6.46 watts per square meter) in an office. That means you need someone like that generating 9.8 watts every 16.3 square feet or 1.5 square meters.

There's an inherent tension there, where sufficient density to make that work would require people to take fewer, shorter steps.

A basketball court is 4700 sq feet (436.6 sq meters). That means you'd need 288 big people stepping that fast, jammed into a single basketball court sized space, just to keep the lights on in that space. If any of the people stop moving even for a second, the system fails to keep up.

The numbers don't make any sense.

A 100kg (220 lb) person whose steps compress the tiles by 1cm (0.01m) per step would be transferring 100 kg x 9.8 m/s^2 x 0.01m = 9.8 joules, or 0.00272 watt hours. That assumes 100% perfect efficiency in capturing that energy.

A watt is a joule per second, so someone who steps 1 step per second is generating 9.8 watts. That's not enough to light the station, much less run the computers and signs and the fare gates and escalators and elevators.

And of course it wouldn't come anywhere close to running the trains. After all, if it were easy to take people's biomechanical power to run trains, that would mean that humans could push the trains effectively.

So they're trying to put 2GW of dispatchable (can be dialed up and down on demand), carbon-free electricity by 2028. If you include the last year and a half of the exploratory drilling work they've done on site, that's about 5 and a half years.

They're also saying that each well is about $5 million, have about 30 wells planned for the 400MW project. Not sure how much going up to 2 GW would increase the cost, but that's $0.33 per watt for the 400 MW plan.

In comparison, Vogtle added 2 nuclear reactors for 2 GW of capacity in Georgia, and it cost $35 billion and took 16 years. That's $17.50 per watt.

Solar is somewhere between $1 to $1.20 per watt, but isn't dispatchable.

Ongoing operational costs might be different between all of the different types of generation, but the up front costs are important enough to where they should be a significant part of the discussion.

So if they can pull this off in a few places, this will go a long way towards actually going to zero carbon on the grid.
